The Cover Page: Ford Circles near √2 Ford circles let us visually understand the world of rational p 1 numbers. A Ford circle is a circle centered at ( q , 2q 2 ) with 1 p radius 2q 2 , where q is an irreducible fraction. Each Ford circle is tangent to the horizontal axis, and no two circles intersect with each other. In fact, one can fit all Ford circles beautifully in the upper half plane. The cover page shows the Ford circles corresponding to those rational numbers near √2. In particular, the bolder colored circles represent the first few 1 3 1 7 terms of the sequence 1, 1 + = 2 , 1 + 1 = , 2 2+ 2 5 1 17 1 + 1 = , . . . , which converges to √2, as the following 2+ 1 12 2+ 2 continued fraction expansion of √2 shows:

√2 = 1+ 1 2+ 1 2 1 + 2 +…

The figure suggests how quickly this sequence converges to √2. As this example shows, with the aid of Ford circles, theories involving rational numbers and continued fractions can be understood from a geometric aspect. Message from Dean Graduate School of Mathematics

Enjoy your journey into mathematics! To those who take up this brochure

Study and research in mathematics are often compared to mountain climbing. This is because the experience of piling up Dean of Graduate School of Mathematics logical steps to reach our goals or of obtaining surprising new prospects by finding unknown routes, viewpoints and concepts is Hiroaki Kanno similar to the experience of mountain climbing. The mathematics you have learned in high school and undergraduate programs is like climbing well-known mountains with a passage leading up to the start point of a mountain trail and a nicely paved path. But, in a graduate program, you often face punishing paths and untrampled routes. I do not necessarily mean forbidding lofty mountains such as the Himalayas. Even in familiar mountains nearby, there might be secret routes and hidden lookout points. It is also appealing to aim at mountains spreading over from mathematics to other academic fields. In recent years, many mountains crossing over the boundaries of mathematics have been discovered, ever expanding the research field of mathematics. If you are considering studying and researching mathematics in graduate school, please contemplate which mountain you would like to climb. I hope that the information on our faculty members and the mind map provided in this brochure will assist you in doing this. In mountain climbing, the higher your goals are, the greater the need is to develop physical strength and to gather background information. Even if you are planning to climb a familiar mountain, to avoid accidents, it is always important to check the weather forecast and to make prudent judgments. Just as in mountain climbing, learning and researching mathematics require considerable preparation and determination. As this brochure carefully explains, it is our belief that our graduate program provides sufficient support systems for you to study and research mathematics. Our basic policy in educational programs stresses fundamental knowledge of mathematics and broad coverage of various fields of it. Based upon this policy, we offer systematically organized courses, a wide variety of intensive courses, and a tutorial program under the supervision of advisors. We are also proud of our excellent library, secure computer network system, and friendly supporting staff. Furthermore, in recent years, we have been strengthening our career planning support.

Perhaps some of you might think that you can do mathematics alone. But, to avoid becoming complacent, you should not neglect communicating with various people. I advise you to keep your intellectual curiosity, to ask questions when you are puzzled, and to try to explain to others when you discover something or solve interesting problems. These days, gathering information has become simple due to the development of the Internet. Yet, it cannot replace face-to-face communication with people from other academic disciplines or from different cultural backgrounds. We provide various opportunities for interaction such as Café David* and many events for international students. I encourage you to seize these opportunities.

One of the biggest goals for a graduate student in mathematics is to submit a masters’ thesis or a doctoral thesis and have it approved by the thesis committee. It can be compared to writing a useful guidebook on a mountain you have investigated and making people interested in that mountain. I would like to invite you to find your favorite mountain and tell others its charm. We, the members of the Graduate School of Mathematics, will gladly help you in that endeavor.

Having just I couldn’t wait to tell her the latest results of my research. attended a summer conference in Poland, I thought The details of the discoveries I had omitted in e-mails from I already knew what the weather would be like in I found easy to articulate here, face-to-face. I am Norway. I should have brought along my warmer outfits! particularly grateful to her for showing genuine pleasure Thinking of what it would cost to buy an appropriate in my findings. Students come to NTNU from all over the jacket here, I sighed deeply, again turning the air into a world. I believe her presence helps to explain why. smoky vapor. The main purpose of this particular visit was to complete After leaving the airport, I enjoyed the beauty of the the final draft of a paper we had collaborated on. It required Nidelva River on the way to the Norwegian University examining the contents minutely as the editing process of Science and Technology (NTNU). I was looking neared its end. Even a slight change can make the entire forward to seeing a familiar face in a certain office article sound more sophisticated. We were also surprised to on the eighth floor at the university. When I got to the find a few conflicting statements. In the process of choosing office, my face was wreathed in smiles. Dr. Reiten and which academic journals to submit the paper to, we spent I were delighted with this reunion. She was waiting days discussing its contents. This also entailed exchanging there with a spare sweater and scarf ready for me. What e-mails with a mathematician in the U.K., also a co-author. a wonderful person she is! It was a series of papers that It took two busy weeks for us to complete the final draft.

I dined out with Professor Reiten the last day before my departure for Japan. We ate our usual fare, a famous fish soup. In the restaurant, I talked about topics my students in Japan are working on. She was cheerful, joking “Osamu, you were born in the very same year in which the Almost Split Exact Sequence was discovered.” A memorial was held celebrating the sixty-fifth birthday of this surprisingly energetic woman in May 2007. On the flight back to Japan, I found myself wondering how much further mathematics will advance while she is still a working scholar. I returned to Nagoya the following day to continue with my research, revitalized by the days in Norway.

e Dav af id C Learning Mathematics at "Cafe David"

The idea of studying mathematics brings images to mind of large lecture halls and rigorous self-study. These traditional methods of study are indeed important, but there are also dynamic alternatives. One of those is to gather various thinkers together to debate and discuss mathematics. The photo is of our own weekly event, “Cafe David”. Here, undergraduate students, graduate students, and teaching faculty gather in a casual cafe meeting style, to chat over both academic and less formal questions. We named "Cafe David" after David Hilbert, the well-known mathematician often said to represent 20th century mathematics. As the name suggests, delicious coffee is on offer for department members in attendance. Discussions here allow many to overcome the common barriers that exist between undergraduate and graduate students, or between students and faculty, or among academic areas or schools, strengthening relationships and intellectual understanding at the same time. In addition, graduate students join “Cafe David” as teaching assistants, offering a comfortable environment to answer tough questions from lectures. Faculty provide assistance here in the form of office hours and students can learn from interaction in this active public learning space. Wouldn’t you like to come and take a look at our diverse learning styles of mathematics?

11 Education Programs

Undergraduate Program

Learning and Lecture Content The following is a brief description of what is offered at Nagoya University for mathematics majors.

Level 0 (Freshman) You will learn differential calculus and linear algebra through examples and by working on exercises. These are the "raw material" of modern mathematics. You will be asked to carry out explicit computations, which will give you access to computational skill, and will foster proper intuition for mathematical concepts. It is of utmost importance that you work through as many problems as possible, gaining exposure to mathematics. Semester Lecture Small Group Class Summer Calculus of one variable/ Linear algebra/ Overview of mathematics Seminar on mathematics

Winter Calculus of several variables/ Linear algebra/ Overview of mathematics Seminar on mathematics

Level 1 (Sophomore) First differential calculus and linear algebra will be reworked rigorously in the language of modern mathematics –sets and maps. Totally new concepts, such as complex function theory and topological spaces will enter the scene. The learning curve is steep, and you will be required to put in a lot of effort and your patience will be taxed, but the reward will be high: an entrance ticket to modern mathematics.

Message from a Foreign Student Junghun Lee Self-introduction My name is Junghun Lee. I come from South Korea. I have been living in Japan since 2008 when I was an undergraduate student. Now I am a graduate student of mathematics of Nagoya University. Daily Life Here let me share a bit about my daily activities. I shall divide it into two parts, study and part-time­ work activities. Study My major is (discrete) dynamical system.I have a seminar twice a week with only my research adviser. Since it is a one-to-­ ­one seminar, each time we can have a lot of talk regarding the topics. Part-­time Work I am working as a research assistant at Nagoya University. The contents of the part-time­ work consist of taking some lectures, and writing feedback about each of them to improve those lectures. For example, sometimes we take IELTS preparation class, participate in some kind of discussion, and take a lecture to be a global leader. Nagoya The location of Nagoya is in the middle of Japan. It is very convenient to go to other places in Japan. Indeed, many graduate students need to either attend or to participate in many conferences, and they are held in many different places, such as Tokyo, Kyoto, or Osaka. I think it is one of the merits that Nagoya is located in the middle of Japan. Moreover, there are many dormitories available for international students in Nagoya. I have been living in Nagoya International Student Center for 4 years. The staff are very kind and helpful to me. It is quite far from Nagoya University, but I enjoy riding a bicycle to commute. Don't worry, if you want to live around Nagoya University, you can also choose dormitories nearer to the university than mine. Nagoya University Nagoya University has a very good environment for studying mathematics. First of all, there are a lot of teachers in various fields such as Mathematical Physics, Algebra, Geometry, Analysis, etc. Every year, they open some classes related to their fields called `Sotsugyou Kenkyuu’ and `Syouninzuu Class’. Each of these is a kind of seminar where the students give presentations one by one and the teacher listens and also gives advice during the seminar. If you want to join this class, you may ask for permission to join to the teacher in charge. Secondly, there are many books and articles in the library of Nagoya University. It is very helpful because we need many references to study mathematics. The library has many references, so we don`t need to buy all of what we need. Finally, I would like to talk about the staff. The staff here are so kind and they help you as long as they can. Everyone can be a friend to the staff. They have many events for international students so that we can enjoy our campus life. Besides, they are really professional in dealing with your problems such as finding financial support, working as a teaching assistant or research assistant, looking for a dormitory, etc.

Level 1 (Junior) You will be introduced to mathematics that was developed in the early 20th century. Level 1 ends with the introduction of Lesbesgue integrals and their application to Fourier analysis, curves and surfaces which generalize circles and spheres, groups and rings that are algebraic abstractions of numbers, polynomials and maps. There will be "Omnibus lectures" on how mathematics relates to the real world and what lies ahead of all this, and "group study" where you pick the text of your choice, discuss the content with your fellow students, give talks, and give a poster presentation. Semester Lecture Small Group Class Summer Introduction to group theory/ Introduction to curves and surfaces Seminar on mathematics Introduction to differential equations/ Lebesgue integrals and measure theory

Winter Rings and polynomials/ Introduction to differential forms Group study Introduction to functional analysis/ Omnibus lectures/ Group study

Level 2 (Senior) Lectures for seniors at Level 2 are open to seniors and graduate students. The subject matter of these lectures differ by year. A partial list of courses offered in the past is given below. There are also numerous "intensive courses" , which typically last for a week, designed to give an overview of research at the forefront. Courses at this level emphasize the diversity and universality of mathematics that can only be appreciated by taking a higher viewpoint. You are not only expected to learn from these courses, but also to develop your own viewpoint/taste for mathematics. Reading courses under faculty supervision are offered, where you will learn how to read a book or a research article, how to formulate your thoughts in a mathematical way, and how to discuss mathematics. Semester Lecture Small Group Class Fields and Galois theory/ Manifolds/ Functional analysis/ Summer Introduction to probability theory/ Introduction to mechanics/ Introduction to numerical analysis/ Omnibus lectures Elliptic curves/ The heat kernel and the index theorem/ Senior reading course Introduction to partial differential equations/ Electromagnetic theory/ Winter Methods in applied mathematics (offered in English)/ Functional programming languages

Fostering Scholars who Investigate, Think, and Discover on their Own The Graduate School of Mathematics aims to cultivate self-motivated individuals, who can successfully navigate inquiry, reflection, and discovery based upon scholarly training in mathematics. Our commitment is to maintaining an enlightening environment for problem- conscious students where, together with scholars and fellow students, they can refine their ideas and apply logical reasoning in seeking solutions to problems.

Intensive Courses Intensive courses are those conducted by lecturers from other universities or institutions, intensively, over short periods of time. Content ranges widely, from those of an introductory nature that require no prior technical knowledge at all, to those that focus more narrowly on the most cutting edge findings in a specific field. Not only are the mathematical fields of Algebra, Geometry, Analysis, Applied Mathematics, and Mathematical Physics covered, but lecturers are brought in to offer various perspectives, including that of the corporate world and practical applications. To find out more information about intensive lectures conducted in 2008 and the small group classes explained below, please see our graduate school’s web page, under “Education & Job Search”.

Small Group Class Small Group Class is a two-semester seminar intended to develop reading, critical thinking, and discussion skills. In the seminar class, students expand upon their learning from faculty lectures and identify their specific focus of interest/ research from within areas presented in lectures. Within the chosen subject area, classes offer multifaceted lectures guided by student interest. The pace of the lectures is tailored to participating students’ needs. As seen from the chart above, students can both improve their skills and explore their chosen field in the small group class. Master's students will belong to a credit-earning seminar each year. At the same time, they are strongly advised to attend another seminar. Students who attend regularly and submit successful assignments will be awarded at most 1 credit over 2 years in addition to the credits from other classes for which they are registered.

Teaching Assistants (TA) Teaching assistant positions are filled primarily by first year master's students. They are hired to aid professors with lectures and seminars for undergraduate students in the first, second, and third year in the science department, as well as others, and to assist with Cafe David. Duties of a TA include designing and correcting class exercises, writing interpretations, and attending all Q & A in and out of class. These duties offer graduate students an opportunity to join the backstage of university lectures. Experiencing lectures from the standpoint of a teacher allows TAs an invaluable opportunity for their future, to learn what it is to teach. In addition, as a TA, they can understand many of the typical problems that students repeat, as well as those of beginning instructors and how to avoid them. Wages are paid to TAs, but many past TAs say that the real value in this assistant position is the opportunity to enhance one’s own learning and future research.

Message from a Foreign Student Ade Irma Suriajaya My name is Ade Irma Suriajaya, but people usually call me Chacha in Japan. I come from Indonesia and now I am in my second year of a master's program in mathematics in Nagoya University. My field of study is analytic number theory, and I am doing research on the zeros of the derivatives of the Riemann zeta function and the Dirichlet L function [under the supervision of Prof. Kohji Matsumoto].

I graduated from a university in China, and, in my third year of undergraduate study, I got an opportunity for a student exchange program at Nagoya University. That was my first time coming to Japan and also the first time I learned Japanese. At that time, my major was Aeronautical Engineering, but since I was really interested in mathematics, I took mathematics classes besides Japanese during that period. In the first semester, since I could not understand Japanese, I took a mathematics class which was given in English. In the second semester, I took some classes in mathematics which were given in Japanese. I was really impressed that the teachers I knew during that period taught me who understood nothing about pure mathematics, very kindly and sincerely. Even when I could not understand Japanese, they all explained well in English, and sometimes even let me ask in English when I could not express my question in Japanese. There is also a space in the building where you can ask any questions related to mathematics. There are some teachers and students there to help you, and it is open everyday during the lunch break. I went there very often, and I found it really helpful for my study. To be honest, the atmosphere around helped and encouraged me so much to master Japanese that I became more and more impressed.

I really felt in love with the study and research environment in the Graduate School of Mathematics of Nagoya University and, of course, with the environment of Nagoya itself. Thanks to the exchange program, not only for giving me the chance to study Japanese, but also for giving me a chance to know this place, which attracted me so much that I finally decided to change my major to mathematics and also to return to the Graduate School of Mathematics of Nagoya University after my graduation in China. That is the reason why I am here right now. Here they have good facilities, such as the study space given to each graduate student, the seminar rooms, and especially the library. They also have good services and they provide various kinds of financial support. Besides scholarships for international students, they also employ students as teaching assistants and research assistants. Here, every student is also provided with some research allowance which we can use to attend a symposium, conference, seminar, etc. either inside or outside Japan. There is still some other financial support, too. Nagoya University itself provides Japanese courses and also some other foreign language courses open to not only exchange students or any particular students, but, as I know, all students. These are some reasons why I do not regret my decision to return here.

People say it is not easy to adapt to a new environment, and the same is true about a new major. I faced difficulties the first time I came to Japan, and I found it really hard to be able to keep up with my peers since I lacked understanding in basic (pure) mathematics. Especially, students of mathematics in Japan are required to do seminars starting when they are in their undergraduate studies. I did not do well in the beginning, and there were so many things which were hard to understand. But many students, including seniors, and teachers understood and helped me along the way. I believe that this also happened to other students as well.

15 Education Programs

Graduate Program for Doctoral Degree (Ph. D.)

Fostering the Next Generation of Young Scholars The primary goal of our doctoral program is to foster the next generation of young mathematicians. They must understand the necessary broad range of skills involved in mathematical sciences and be prepared to apply them appropriately to various problems. The doctoral program, in particular, requires self-driven learning, including discovering problems on one’s own and building the skills necessary to solve them. Sending our PhD holders equipped with these skills as competitive professionals out into society is the ultimate goal.

Active Student Body Our current doctoral students are involved in student organized seminars on campus, as well as the planning and organizing of national academic conferences for young scholars. This is in addition to active independent research of their own. We believe this combination of activities results in the high quality research output our department’s doctoral students produce. Among other activities, Student Projects have received strong support from our department, as well as from the Program for Enhancing Systematic Education in Graduate Schools since 2007.

JSPS Fellows This program was established by JSPS (Japan Society for the Promotion of Science) to assist promising and highly qualified students wishing to conduct research in universities or institutions. Fellowships are awarded for a period of two to three years with monthly research-related expenses and Grants-in-Aid for Scientific Research. Detailed information is provided at: http://www.jsps.go.jp/english/index.html

Interdisciplinary Research Mathematics has historically influenced other fields, and, at the same time, evolved itself from the influence of other research fields. Nowadays, working towards a goal of broad global exchange is not enough. Conducting research with a vision beyond our own narrow fields is also required. Our department makes a unique effort to strive towards working with scholars of interdisciplinary research, and also with the Graduate School of Information Science, in order to further this goal.

Message from Foreign Student Xin DONG

From China, I grew up in Harbin and studied in Shanghai since high school. Before my current study I joined an academic exchange program called NUPACE, allowing me to spend one semester at Nagoya University. After experiencing the excellent research environment at Graduate School of Mathematics, I decided to do my PhD here under the G30 International Program.

My interest is on Several Complex Variable and Complex Geometry and I belong to an active group working in this area led by Prof. Ohsawa. I am now focusing on topics around the Bergman kernel, setting up appropriate research goals and trying to accomplish them. Much joy would arise after the achieving of new results, since it represents that the perspective on a certain mathematical objects has deepened. During the attendance of domestic and international conferences, I had the opportunity to meet many mathematicians full of original ideas who greatly inspired me. I am a TA for mathematics courses taught in English for international students. For teaching, here I also see professors explaining good mathematics to non-experts in simple words, so that more people can enjoy the beauty of mathematics and share the joy.

At the second year, I spent much time and efforts applying for a fellowship sponsored by JSPS which is competitive. Fortunately heading to the interview process, I still have no idea what to prepare before consulting Prof. Nayatani, who later arranged for me two mock interviews. And I clearly remembered one morning seven professors from the department showed up out of their busy schedules, evaluating my speech and offering valuable comments. Looking backward, I feel it not only a self-improvement but also a warm encouragement.

Life in Nagoya is comfortable. The University has various Japanese language classes, as well as various sports clubs, Aikido, Karate, etc. The science library has a large collection where you can read original Japanese references written by professors Kodaira, Oka, which is so cool. The city has a perfect size and the downtown is just ten minutes away by metro. Mountains are always available for hiking and people are kind-hearted. After Japan, I plan to go to America, but wherever I go the experience here has always been great.

19 International Activities

International Conferences of the Graduate School of Mathematics Conference on Resolution of Singularities and the McKay Correspondence 2012 The Nagoya International Mathematical Conference is a meeting held by the Graduate School of Mathematics of Nagoya University every year since 2001. The title of the 2012 meeting was "Conference on Resolution of Singularities and the McKay Correspondence." While there were two small meetings on the McKay correspondence held here before, this conference in 2012 was much larger, and there were a number of participants from different countries. The topics of the talks were related to several fields, such as algebraic geometry, ring theory, and representation theory. The participants enjoyed the fruitful talks and discussions as well as Japanese food and culture. Many of them were the JSPS researchers before, and they were also happy revisiting Japan.

The Global 30 Project - Bringing Nagoya University to the World In July 2009, the selection results of the 2009 Project for Establishing Core Universities for Internationalization (Global 30) were announced, with Nagoya University standing out as one of the Global 30 leaders. The objectives of Global 30 are to strengthen the international competitiveness of Japanese higher education and to offer an education with standards that appeal to foreign students while, through creating an environment where Japanese students work together with international students, fostering highly educated individuals who can be active internationally. The project comprehensively supports a plan to create universities that act as bases for internationalization by providing both the high level of education expected from universities and environments that make studying in Japan more accessible for overseas students. To lead Japan's universities toward internationalization, Nagoya University must transform itself into a "university of the world". This means building a new environment in which Japanese and international students work side by side. In this way, the high standards of undergraduate and graduate education Nagoya University has achieved will be more widely accessible to students from overseas, and the University will be able to educate individuals with the ability to interact on the world stage. Here are some of the strategic measures being taken to realize this goal. from http://www.nagoya-u.ac.jp/en/international/edu-act/g30/ Mathematics without Borders Mathematics has no borders. No matter what nationality they are, mathematicians around the world strive each day through their research to advance the development of mathematics. Among them, there are always researchers out there somewhere pursuing answers to the same problems. Therefore, it can be said that the exchange of information regarding research is extremely important. In order to exchange this up to date information our school works hard to promote and offer various conferences, intensive courses, seminars, and workshops. In this vein, we have established formal academic alliances with the Korean Institute for Advanced Study (KIAS), Paris 7 Denis Diderot University, etc. With them, we have conducted cooperative research workshops and the exchange of graduate students as research assistants. Exchange beyond Fields Mathematics has historically influenced other fields, and at the same time evolved itself, from the influence of other research fields.Nowadays, working towards a goal of broad global exchange is not enough.Conducting research with a vision beyond our own narrow fields is also required. Our department makes a unique effort to strive towards working with scholars of interdisciplinary research, and also with the Graduate School of Information Science, in order to further this goal.

Message from a Master Student Hei Ze I’m Hei Ze, a master student from China, this is not the first time I come to Japan, I have studied in Kumamoto University for one year as an exchange student, therefore when I come to Nagoya University, I’m not surprised by the convenience of the transportation, the cleanness of the campus, and the kindness of all the staffs and teachers in Nagoya University, however I’m still impressed by the great academic atmosphere here, such as the huge display board hanging on the wall of the corridor at the Mathematics Bldg. introducing the Riemann hypothesis and the history of group theory. I major in physics when undergraduate, so at the beginning of the first semester I really afraid that I will be failed in taking the specialized courses in mathematics, and soon I found I have worried too much, the courses are proceed step by step, so if you have attended all the courses, there will be no difficulty in getting the credits. In Nagoya University, there will be a seminar every week hold by the students whose research is same or similar, it’s a good opportunity for you to communicate with other students about what you have learned this week, and it will push you to learn because you have to make presentation at the seminar, and it needs careful preparation, I think this is a really efficient way of learning mathematics. At last I want to introduce my supervisor Prof. Kanno, he is a kindness teacher and a rigorous scholar. At the first time of the seminar, I haven’t prepared well for the presentation, I felt shameful and guilty, however finally I finished it under the rigorous and detailed guidance of Prof. Kanno, and I really appreciate the patience he showed to me at that time. Above all I think Nagoya University is a place full of humane care and academic atmosphere, and I really enjoy the life here.

21 Academic Cooperation Programs Our Graduate School has several academic exchange programs shared with worldwide institutions to promote and develop cooperation in the field of mathematical sciences through the following activities:

Exchange of faculty and students. Exchange of publications and other academic materials. Bilateral symposia and workshops. Meetings to improve mutual research and educational programs. Mutual student managed projects.

Here is the list of institutions in cooperation agreement as of May 2012: Department of Mathematics, Nanjing University, since 2012.

We are committed to continue offering various activities that foster chances to talk to new people, promote deeper understanding of Japanese culture, and allow students to experience different cultures. Through these events, we hope to help the members of our community to appreciate each other’s languages, cultures, and values, and to respect each other’s viewpoints.

23 Support for Education and Research

Staff from across many sections and areas are involved in the life and operation of the School of Science and Department of Mathematics. The sections introduced here are an important part of our support structures.

Science Library A fully developed library is a quintessential element in providing a quality mathematics education, and thus our Science Library has served us well as the “face” of our department. The library houses over 100,000 volumes related to mathematical science and more than 1,600 periodicals, 90% of which are published overseas. One of our highlights is the Hilbert Collection, with copies of nearly 10,000 academic papers that the greatest mathematician, David Hilbert (1862-1943), owned. It has become a valuable resource for research. Books of reference, including textbooks, are found in the student reference section in order to promote easy access for students. Online search catalogs are fully equiped for easy access to books and electronic journals, and librarians offer support to users seeking further information.

Computers and Networks Electronic journals and e-mail are some of the modern indispensable tools for computer networking for researchers in mathematical science. Computer laboratories are located in the Graduate School of Mathematics Building (2 rooms) and in Science Building A (1 room). All PCs are connected to the intra-campus network (NICE), which offers reliable high-speed access to the Internet. This computer network environment corresponds to the needs of both graduate students and faculty for exchanging scholastic information. Our department is committed to enhancing our information technology environment as a research tool, not only as a scaffold of numerical analysis and information science, but also for theoretical development by installing various mathematical software programs.

Office of Academic Affairs The Office of Academic Affairs was established in 2003 in order to provide specific services needed by students and faculty. In 2008, it was reorganized to deal with all educational affairs. For students and faculty, the office processes research grants (Grants-in-Aid for Scientific Research) and student aid to attend workshops, and manages study rooms and locker keys. To assist department activities, the office edits mathematical journals, publishes information in the form of brochures, updates web sites, prepares to hold international conferences, such as Nagoya International Conference, and hosts foreign visitors. The office aims at creating better academic surroundings with prompt service responding to department needs, with a friendly atmosphere as their motto.

Nagoya Mathematical Journal Known as a comprehensive academic journal for mathematics, Nagoya Mathematical Journal (NMJ) has long been highly evaluated internationally since its first edition published by our department in June of 1950. All back numbers are available as electronic archives, and can be accessed through a database called Project Euclid by the library of Cornell University. While reviewing many creative mathematical papers submitted to the journal from around the world, editing committees make a substantial effort to maintain its scholastic quality. We firmly believe that the academic value of NMJ depends on the advanced level of mathematics with which our department deals. We are proud of NMJ as proof of the depth of our history and the excellence shown by mathematicians in Nagoya. http://projecteuclid.org/Dienst/Ul/1.0/ Journal?authority=euclid.nmj

Administration Office The Administration Office of our department supports faculty and students by maintaining campus facilities, purchasing office supplies, and arranging research and business trips. The office, for example, takes care of air-conditioning for computer laboratories and classrooms. Its constant effort provides faculty and students with a comfortable environment for research and study and the smooth arrangement of facility use and meetings. Accordingly, the office plays an important role for both faculty and students, helping them to focus on their business within a comfortable campus, doing its best to offer speedy and accurate service.
